# Review Project Rubric

Today you will continue to work on your project with your partner.

- Before you start, review the project rubric.

Today you will continue to work on your project with your partner.

- Before you start, review the project rubric.

Work on your project and evaluate your progress using the project rubric.

Today, you and your partner should try to complete the following steps.

- Sketch a scale version of the nets for your model buildings using the inch grid. Remember, your scale is 20 ft to 1 in. The net for the sliced prism will be tricky to draw and will require some guesswork with regard to finding the proper angles and lengths. Think about ways to construct the slice.
- Using your scale drawings as guides, draw the actual nets for each building on 1-inch grid paper. Cut out each net.
- Construct each model. Adjust the cut on the sliced building if you need to.
- Mount the models on their bases.
- Find the surface area of the full-size buildings and the model buildings. Show your work and justify each step. Note that your calculations (particularly for the sliced surface) will be estimates rather than exact measures.
- Find the volume of the full-size buildings and the model buildings. Show your work and justify each step.

- As you work, use the project rubric to evaluate your progress and make sure you are on the right track.

Take notes about your classmates’ successes and failures to gain insight into ways that you might improve your project.

Complete this Self Check by yourself.

Use the drawings to answer the following questions. Note that the surface areas of the top and bottom surfaces will not be the same because the prism has been sliced. For the same reason, the surface areas of the side surfaces will be different.

- What is the length and width of the rectangle cross section revealed?
- What is the surface area of the figure? Show how you found your answer.
- What is the volume of the figure? Show how you found your answer.
